You are not welcomed.
The gleaming fangs and paws are a clear warning, fitting given the title’s “welcome.” This cat has made this box his own, and the owners have been kind enough to put a sign at the door. Please enter at your own risk!
Boxes, like moths to light bulbs, attract cats strangely intoxicated, using them as hiding places for tactical sneak attacks or makeshift beds. The box’s four walls offer protection and important value to the environment. He may see if the person who enraged them is approaching from the comfort of his cage. They’ll sneak attack your ankles from behind while you’re unaware because they can detect you from the safety of their cage.
